Basically everything. Installation, patching, gameplay, etc
What does not
Cinematic Depth of Field (leaves cutscenes with strange black textures).
Performance is terrible.
The launcher cannot be properly interacted with (only part of the links are clickable). The game can be run directly, however. Also the performance checker doesn't work.
GLSL needs to be disabled.
What was not tested
I tested the game with a full playthrough. Encountered no bugs not mentioned above.
vcrun2010 was installed (required to run the launcher), d3d9 is required as well (both easily installed via Winetricks). "UseGLSL = disabled" in the registry. Sometimes had issues with sound if Pulseaudio wasn't disabled (although it generally worked). Performance is ungodly slow. I finally had generally okay performance if my resolution was set to 1152x768 and I set the profile to Low in the configuration. I was able to then disable texture downscaling and crank up settings. Low gives some slightly different internal LOD and Max Texture sizes. Performance was completely hampered in a specific level (Vergen) during rainy weather. My system is a Q9550 and a GTX460 (768MB variant) with 2G of RAM. Windows users reported good performance (30-50fps) at stock High settings and a resolution of around 1080p. Admin note: rating changed to conform to the rating definitions.
